When your Mac is listening, it displays a microphone to the left or right of the page, aligned with the insertion point. If you turn on advanced dictation commands, the microphone appears in the lower-right corner of your screen, and you can drag it to another position. When your Mac can hear you, the input meter inside the microphone rises and falls as you speak.

Speak the words that you want your Mac to type. Dictation learns the characteristics of your voice and adapts to your accent, so the more you use it, the better it understands you. If it doesn't understand you, learn what to do.

Without Enhanced Dictation, your spoken words and certain other data are sent to Apple to be converted into text and help your Mac understand what you mean. As a result, your Mac must be connected to the Internet, your words might not convert to text as quickly, and you can speak for no more than 40 seconds at a time (30 seconds in OS X Yosemite or earlier).

To use dictation on your iPhone, iPad, or iPod touch, tap the microphone on the onscreen keyboard, then speak. Consult your iPhone or iPad user guide for details.

If the Slow Keys or Sticky Keys feature is turned on in the Accessibility pane of System Preferences, the default keyboard shortcuts for dictation might not work. If you need to use those accessibility features, create a custom dictation shortcut: Choose Apple menu > System Preferences, click Keyboard, click Dictation, then choose “Customize” from the Shortcut menu.
